T0 all whom, t may concern:

Be it known that l, FRITZ BAUKE, a subl ject of the King of Prussia, German Eml peror, and a resident of 3 Lindenstrasse, Berlin, Kingdom of Prussia, German Emg pire, enL ineer, have invented certain new and l useful mprovements in Sucking Gas-Grenerators, of which the following is an exact specification.

My invention relates to a device to be provided at such sucking gas generators in which carbonaceous material is gasifled in a feeding-shaft and the distillation-gases are I carried away by a specific sucking power. It is necessary at such generators for the purpose of obtaining a working of the generator without difficulty that the two sucking forcesgviz., the principal working power and the sucking power serving for leading off the tar-gases-do not interfere with each other, and, furthermore, provisions must be made that the resistance of the combustibles to be gasified in the feeding-shaft remains as invariable as possible. These requirements are fulfilled in defective manner if the carbon is strongly baking and if such carbon is used at which the remainders of the distillable constituents canjbe driven out only by a longer heating, especially if the carbon not perfectly gasified is easily coherent, thereby causing that the resistance just in the gasifyzone is variable. Owing to this fact either the whole working of the generator is disturbed or a uniform composition of the O' tdvercome these defects according to my invention, a device in the shape of a hollow body opened in a downward direction is arranged within the feeding-shaft near or at the lower end of the latter, and this body may be adapted to be rotated or moved up and down. By means of this hollow body a hollow space is produced within the feedingshaft immediately above the iire zone or the reduction Zone of the furnace, whereby the radiating heat of the fire Zone is permitted to act directly upon the material to be distilled in the feeding-shaft, since the heat of the fire zone will readily pass through the hollow Space and the hollow body and cause a perfect distillation of the material. In the known furnaces of this type the heat of the nre Zone will be prevented from passing to the material within the feeding-shaft by the ases produced cannot be obtained. To.

layers of the fuel arranged immediately at the end of the feeding-shaft', so that the time t required for the distillation lasts very long or the distillation is imperfect. Furthermore, the arrangement can be used as a shaking device for causing the carbon to be piled up uniformly in the feeding-shaft.

In order to make my invention clear, reference is made to the accompanying drawings, in which Figure l is a vertical section of my apparatus according to my invention, and Fig. 2 is a horizontal cross-section on line A B of l Fig. '1.

a is a gas-producer, b is the feeding-shaft, and c the pipe branch for the principal suckmg power.

d is an injector by means of which, through the tube e e, the tar-gases are sucked off from the upper part f of the feeding-shaft, and after being mixed with air or steam, or with both, the mediumsat g are introduced into the reduction zone.

h is a connecting-rod, and h is a hollow cone open in a downward direction for producing a hollow space withinl the fuel of the feeding shaft immediately above the Jlire zone and leaving a small passage for the fuel descending to the fire Zone formed between the fire-grate and the lower edge of the feeding-shaft l). The hollow cone can be turned or raised and lowered by means of the lever t, mounted in the upper part of the generator and connected with the cone by the rod h.

c is a hopper through which the material to be gasi'fied is introduced into the feedingshaft.

In the arrangement provided for rotating the rod 7L and the hollow body h the rod t, provided with a handle, is mounted in the hollow lever t, which in turn is mounted by means of the pivots p in the brackets p. At the free end of the rod i a bevel-wheel m is fiXedly arranged, gearing with the bevelwheel n, carried by the rod h. On the latter a collar n3 is rotatably but unslidably arranged. nz are pins extending from the collar n3 and in engagement with the fork n', secured to the lever i. The slots in the fork n', through which the pins n2 project, are of an oval shape in order to permit up-anddown motion of the rod h by means of the lever i.

The operation of the foregoing-described arrangement will easily be understood. The rod h can vertically be reciprocated by oscillating the lever i and the rod t', and the rod can be rotated .by turning the rod i. It will IOO be observed that the teeth of the bevelwheels n and m must be constructed in such manner that an oscillation of the lever i and the rod t" is permitted without that jamming of the teeth takes place-that is to say, depth of a cog must be sufficient to prevent such a jamming.

Having now particularly described the nature of my invention, what I desire to secure by Letters Patent of the United States 1s- 1. A sucking gas-producer, comprising in combination: an outer shaft, a feeding-shaft forming an annular space with the latter, and a hollow body at the lower end of said feeding-shaft constructed to produce a hollow space within the fuel of the feeding-shaft immediately above the fire Zone `of the gasproducer, for the purpose as described.

2. A sucking gas-producer comprising in combination; an outer shaft7 a feeding-shaft forming an annular space with the latter, and a hollow cone at the lower end of the feedingshaft constructed to produce a hollow space within the fuel of the feeding-shaft immediately above the fire zone of the gas producer, and leaving a small annular passage for the the fuel, for the purpose as described.

3. A sucking gas-producer comprising in combination: an outer shaft, a feeding-shaft forming an annular space with the latter, and a hollow cone at the lower end of the feedingshaft constructed to produce a hollow space within the fuel of the feeding-shaft immediately above the fire Zone of the gas-producer, and leaving a small annular passage for the fuel, and means for rotating and reciprocating the hollow cone, and a connecting-rod for connecting the hollow cone with said means, for the purpose as described.

In witness whereof I have hereunto set my hand in the presence of two witnesses,

FRITZ BAUKE. Witnesses:
